Study Comparing Budesonide Hydrofluoroalkane (HFA) vs Chlorofluorocarbon (CFC) Pressurized Metered Dose Inhalers (pMDI) in Patients With Mild to Moderate Asthma - Full Text View

Sponsored by:	AstraZeneca
Information provided by:	AstraZeneca
ClinicalTrials.gov Identifier:	NCT00667992

Purpose

This study is being carried out to see if budesonide with HFA is effective, safe and well tolerated compared with budesonide CFC. Budesonide HFA has been already given in other research studies, in both healthy volunteers and subjects with asthma.

Study Type:	Interventional
Study Design:	Treatment, Randomized, Open Label, Crossover Assignment, Bio-equivalence Study
Official Title:	A Phase 3, Randomised, Open-Label, Crossover Study to Compare HFA vs CFC pMDI Formulations of Budesonide on Methacholine Hyper-Reactivity in Patients With Stable, Persistent, Mild to Moderate Asthma

Further study details as provided by AstraZeneca:

Primary Outcome Measures:

Change from pooled baseline (i.e., post run-in or washout periods) in methacholine airway responsiveness measured as the provocative concentration of methacholine (PC20) that causes a 20% drop in FEV1 for each treatment [ Time Frame: The methacholine challenge test will entail the patient inhaling from an aerosol containing doubling concentrations of methacholine over a period of 2 minutes until FEV1 has been reduced by 20%. ] [ Designated as safety issue: No ]

Secondary Outcome Measures:

Change from pooled baseline in PEF, FEV1 and Forced Expiratory Flow (FEF25-75) for each treatment [ Time Frame: PEF, FEV1 and Forced Expiratory Flow (FEF25-75) will be measured at each visit from Visit 2 to Visit 7. ] [ Designated as safety issue: No ]
Change from pooled baseline in exhaled NO for each treatment [ Time Frame: Tidal exhaled nitric oxide (eNO) will be measured at each visit from Visit 2 to Visit 7. ] [ Designated as safety issue: No ]
Asthma symptom scores (day, night and total) and rescue use consumption (day, night and total) for each treatment. [ Time Frame: Subjects will be asked to record information twice daily onto a paper diary card (Visit 1-7). ] [ Designated as safety issue: No ]
Change in pooled baseline for morning PEF [ Time Frame: From daily diary ] [ Designated as safety issue: No ]

Estimated Enrollment:	60
